No full textLissodendoryx (Anomodoryx) vulcanus Cavalcanti, Santos & Pinheiro, 2014 (Figure 3) Lissodendoryx (Anomodoryx) vulcanus Cavalcanti et al. (2014): p. 497. Examined material: UFPEPOR 3249, off Boa Viagem Beach (8° 9’ 9” S, 34° 45’ 8” W, Recife, Pernambuco, Brazil), 27 m depth, dredging, st. IV, coll. Recife Expedition (Jan/19/1967). Description: External morphology (Fig 3A): Fragmented specimen, largest fragment measuring 6 cm. Thin transparent peelable film on the ectosome. Smooth surface, fragile consistency, oscules were not observed. Color is beige when preserved (80% ethanol), color in life is unknown. Skeleton (Fig 3B): Ectosome consists of a palisade of tylotes forming a detachable film, with abundant spongin fibers. Choanosomal skeleton a dense, albeit loose reticulation of tylotes, with raphides strewn in confusion in between. Microscleres irregularly distributed. Spicules (Fig 3C–F). Tylotes (293– 448.4 –525 / 4– 5.6 –7 µm): thin, smooth, curved to sinuous, rounded tyles, with slight prominence, sometimes styloid or strongyloid (Fig 3C). Raphides (68– 111.9 –124 µm): elongated, thin, straight to slightly curved, smooth, needle-like tips (Fig 3D). Arcuate isochelae (14– 18.5 –27 µm): slightly curved axis, short and curved alae (Fig 3E). Sigmas (24– 36.7 –46 µm): thin, smooth, curved, “C”-shaped (Fig 3F). Ecology: The specimen was collected by dredging off Boa Viagem Beach (Recife, Pernambuco State, Brazil), at 27 m depth, on sandy bottom. The specimen was associated with Tedania (Tedania) ignis (Duchassaing & Michelotti, 1864). Geographic distribution: Brazilian endemic registered from Rio Grande do Norte State (Cavalcanti et al. 2014), and now from Pernambuco State (present study). Remarks: The analyzed specimen was assigned as a member of the subgenus L. (Anomodoryx) because it has only tylotes as megasclere. From this, it was identified as L. (Anomodoryx) vulcanus due to its skeletal architecture and spicular set being similar to that exhibited by the holotype (Cavalcanti et al. 2014). Because the present materials comprise only fragments, it was not possible to observe the morphological characteristics described for the holotype from Rio Grande do Norte State. With this record, we expand the bathymetric occurrence to shallower waters (27 m depth), previously only known from 108 m depth (Cavalcanti et al. 2014).Published as part of Barros, Thales, Cavalcanti, Thaynã, Hajdu, Eduardo & Pinheiro, Ulisses, 2023, Lissodendoryx Topsent, 1892 (Poecilosclerida: Coelosphaeridae) from Brazil: a new species and transfer of Strongylacidon oxychaetum Menegola, Santos, Moraes & Muricy, 2012 to the genus Lissodendoryx, pp. 401-412 in Zootaxa 5336 (3) on pages 405-406, DOI: 10.11646/zootaxa.5336.3.6, http://zenodo.org/record/828171

Muricy, 17 March 1988. Morphology: The specimens are similar in size and shape, with tubular shape and apical osculum surrounded by a delicate fringe of trichoxeas (Fig. 7A). The peduncle is white in live specimens and brownish/orange in ethanolpreserved specimens, but the peduncle is brownish/orange. The surface is slightly hispid due to the trichoxeas of the cortical region. The atrial cavity is hispid and fills the entire body of the specimens. The aquiferous system is syconoid. Anatomy: The cortical region has several broken spicules. It is mostly formed by giant tetractines with long apical actines. Triactines are also present, but they are less abundant (Fig. 7B and C). Trichoxeas are abundant throughout the entire cortex (Fig. 7D) and may reach the choanosome (Fig. 7E). The subatrial region is comprised exclusively of triactines. They vary in size, but the unpaired actine is always long (Fig. 7C). The atrial skeleton is comprised of tetractines (Fig. 7F). Spicules (Table 4; Fig. 8): Trichoxeas: Very thin, fusiform with sharp tips. Straight or slightly curved. Mostly broken (Fig. 7D). Cortical triactines (Fig. 8A): Conical with blunt tips. The paired actines are slightly curved. The unpaired actine is straight. Cortical tetractines (Fig. 8B): Conical with blunt tips. The paired actines are slightly curved, as well as the unpaired one. The apical actine is straight and long. Subatrial triactines (Fig. 8C): Conical to slightly conical and blunt. Paired actines are short and straight. The unpaired actine is straight. Atrial tetractines: Slightly conical and sharp. Paired actines are slightly curved and larger or the same size as the apical actine. The unpaired actine is straight and longer than the other actines. The apical actine is straight (Fig. 8D). Remarks: Amphoriscus pedunculatus was recently described (Klautau et al. 2017), with an original description in which important taxonomic characters were fully described and illustrated. The redescription provided in the present study differs only with respect to the tips of the spicules: cortical and subatrial spicules are described here as having blunt tips while they were reported as being sharp in the original description. In our opinion, the differentiation between blunt and sharp tips may not always be obvious, but the availability of images (as in Figure 8) helps resolve any doubts. Slight differences were also found in the measurements of the cortical tetractines of the holotype: according to Klautau et al. (2017), the range observed in the length of the unpaired actine is larger (120.0– 238.5 ±58.2–350.0 µm) than that obtained here (177.8– 182.9 ±7.2–188.0 µm). These differences may be related to the existence of several microscopical slides containing dissociated spicules, and the largest spicules may not be evenly distributed. Among the species with peduncle, Amphoriscus pedunculatus is the only one with a subatrial skeleton formed exclusively by triactines. The remaining species, A. chrysalis, A. cyathiscus, and A. testiparus, have both triactines and tetractines or only tetractines. Distribution: The species seems to be restricted to the southeastern Brazilian coast in São Sebastião (São Paulo state), and Arraial do Cabo (Rio de Janeiro state) (Klautau et al. 2017). Distribution: São Sebastião (São Paulo state) and Arraial do Cabo (Rio de Janeiro state).

(holotype B [100248237] image!, isotype CEN [fragm.]!). Figs. 9A–F, 18. Subshrubs 37–150 cm tall; stems erect, indumentum strigose, one-armed trichomes, mixed with sparse glandular trichomes, ca. 0.5 mm long; internodes 0.5–2 cm long; brachyblasts absent. Leaves opposite, chartaceous to coriaceous, sessile to petiolate, petioles ca. 1 mm long, blades 15–35 × 2–10 mm, narrow-ovate, oblong to elliptic, apex acute, base subcordate to truncate, margin subrevolute, both surfaces glabrous to sparsely strigose, one-armed trichomes; brochidodromous, sometimes the secondary veins incospicuous. Racemes 6–15 cm long, frondose, simple to compound, elongated, indistinct; bracts 9–30 × 3–8 mm, subequal pairs, similar to leaves in shape and indumentum. Flowers alternate; pedicels 5–6 mm long; bracteoles ca. 1 mm long, broad-ovate; floral tubes 15–21 mm long; spur saccate, strongly deflexed; outer surface yellow-green, indumentum densely glandular, rarely erect eglandular trichomes <0.5 mm long present; inner surface villous behind the stamens, densely pilose around the ovary, pilose on the rest of the floral tube; petals 6, pale yellow, subequal, ca. 2.5–3 × 1 mm, narrow-obovate; stamens free in the upper third of the floral tube, five antesepalous exserted, four antepetalous subexserted; pistil ca. 16 mm long; ovary glabrous; style glabrous; ovules 3; nectary ca. 1 × 1.3 mm, deflexed. Seeds number unknown, 3–3.2 × 2.3–2.7 mm, narrow-elliptic to suborbicular, apex obtuse to slightly retuse, base obtuse, margin obtuse. Phenology: —Collected with flowers in January, March, and July; fruits in January and July. Distribution and habitat: — Venezuela, in Bolívar state (Fig. 18); river beaches, in savannas; 390–430 m elev. Conservation status: — Cuphea congesta was categorized as Data Deficient (DD), a classification influenced by the low number of specimens found, leaving it uncertain whether the species has a sampling deficit or if it is rare in the region. Specimens examined: — VENEZUELA.

Canaima, 08 January 1973, Schwabe s.n. [58] (B [100248238] image!); Canaima, 09 January 1973, López-Palacios 3062 (P!). Cuphea congesta is identified by the long yellow-green floral tubes, 15–21 mm long, with saccate spur, the pale yellow petals, and large seeds (Fig. 9F), 3–3.2 mm long. It is endemic to Venezuela, occurring in the state of Bolívar within the Guiana Shield, with sparse records in the savannas of Canaima National Park and adjacent regions. Cuphea congesta is morphologically similar to the sympatric C. anisoclada. The smaller floral tubes (Fig. 6C), 10–13 mm long, with obtuse spur, and smaller seeds, 1.7–1.8 mm long, differentiate C. anisoclada from C. congesta. Graham & Cavalcanti (1999a) classified C. congesta in C. sect. Melvilla because of the long, thick floral tubes. Within the section, it was placed in C. subsect. Pachycalyx Koehne (1877: 230) due to the low number of ovules, nonciliate sepals and the South American distribution (Graham & Cavalcanti 1999a). On the other hand, it was observed that C. congesta has several synapomorphies of C. sect. Trispermum s.l., such as pollen grains with thickened exine between the pores (Graham & Cavalcanti 1999a), 3 ovules, deflexed nectary, and obtuse margin seeds. According to Graham et al. (2006) and Barber et al. (2010), the large floral tubes that define C. sect. Melvilla appear to be convergences related to adaptation to large pollinators, such as birds and bees, which are attracted by the color of the floral tube and the nectar that accumulates in the spur. In this way, C. congesta was transferred to C. sect. Trispermum s.l. in this revision.Published as part of Facco, Marlon Garlet & Cavalcanti, Taciana Barbosa, 2023, Taxonomic Revision of Cuphea sect.

Figs. 9G–M, 21. Subshrubs 30–100 cm tall; stems erect, indumentum strigose, with one-armed trichomes, and pubescent, eglandular trichomes erect to appressed, <0.5 mm long, mixed with glandular trichomes ca. 1 mm long; internodes 0.5–1 cm long; brachyblasts absent. Leaves opposite, coriaceous, petioles ca. 1 mm long, blades 15–45 × 1.5–4 mm, linear, apex acute, base acute, margin plane to subrevolute, indumentum strigose on both surfaces, with one-armed trichomes, sometimes sparse glandular trichomes on main vein on abaxial surface; hyphodromous, secondary veins rarely visible. Racemes 1.5–4 cm long, bracteose to frondose-bracteose, compound, contracted at apex of branches; bracts 3–20 × 0.8–2 mm, subequal pairs, linear, rarely narrow-ovate, similar to leaves in indumentum. Flowers alternate; pedicels 4–6 mm long; bracteoles 0.7–1 mm long, ovate; floral tubes 7–9 mm long; spur obtuse to saccate, slightly horizontal to deflexed; outer surface purple on dorsal region, green ventrally, indumentum strigose, mixed with short glandular trichomes, <0.5 mm long; inner surface villous behind the stamens, pilose in the lower third of the floral tube; petals 6, white, unequal, the dorsal ones smaller and narrower than the ventral ones, two dorsal 2.2–3.7 × 0.8–1.3 mm, narrowobovate, four ventral 4–5 × 1.8–2.5 mm, narrow-obovate to obovate; stamens free in the upper third of the floral tube, five antesepalous exserted, four antepetalous subexserted; pistil 5–7,3 mm long; ovary glabrous, rarely slightly pilose; style pilose in the basal portion or glabrous; ovules 3–4; nectary ca. 0.8 × 1.2 mm, deflexed. Seeds 2–4, 1.7–2.1 × 1.6–2 mm, broad-obovate, apex slightly retuse, base acute, margin obtuse. Phenology: —Collected with flowers and fruits from October to February. Distribution and habitat: — Brazil, in northeastern Goiás state (Fig. 21); sandy riverbanks, gallery forest edges, and “campos rupestres” on sandy soil; 800–1100 m. Conservation status: — Cuphea cunninghamiifolia was categorized as Endangered (EN) B1ab(iii)+2ab(iii), with EOO of 657 km ² and AOO of 20 km ². It is the same category as in the assessment published by the Red List of Brazilian flora (CNCFlora 2023). Although its distribution is practically comprised by the Chapada dos Veadeiros National Park, it should be considered that populations of C. cunninghamiifolia are rare, threatened by anthropogenic fires and disordered tourism (CNCFlora 2023). Furthermore, the pressure of agricultural activities around the park is worrying, considering the current weakening of Brazilian environmental policies (MapBiomas 2021). Specimens examined: —BRAZIL.

The Oratione alli fuoriusciti di Fiorenza et altri cittadini amatori della libertà (1556). For an attribution to Bartolomeo Cavalcanti
No full textThe essay gives a new contribution to the study of forentine political exile through the publication and the analysis of an unpublished text: the oratione alli fuorusciti di Fiorenza et altri cittadini amatori della libertà. Almost forgotten by historians, the document proves the vitality of the republican spirit. After the truce of Vaucelles and despite the recent defeats in war (Marciano and Siena), it in fact shows that the hope of disengaging from the tyranny of the Medici family was still in the exiles' environment. According to a series of cultural, rhetorical and ideological elements the suggestive hypothesis that the author of the text is Bartolomeo Cavalcanti is brought forward. Bartolomeo Cavalcanti was a famous literary figure and diplomat and one of the main Florentine Diaspora representatives. In those years he was living in Rome on behalf of the Farnese family and would shortly be entering the service of cardinal François de Tournon

Association of alpha b-crystallin expression with tumor differentiation grade in colorectal cancer patients. [*Pagano C. first author]
No full textAlpha B-crystallin (CRYAB, HSPB5) belongs to the small heat shock protein (HSP) family and is highly expressed in various human cancers, suggesting a crucial role in tumor progression. However, few studies have examined CRYAB expression in colorectal cancer (CRC). In the present study, we investigated the relationship between CRYAB expression and the clinicopathological features of CRC samples. We comparatively analyzed CRYAB protein expression in 111 CRC tissues and normal adjacent colonic tissue, observing that it was significantly lower in CRC tissues than in corresponding non-cancerous tissues. Moreover, immunohistochemical analysis showed a significant correlation between CRYAB expression and high histological grade G3 (p = 0.033). In summary, our results point to its possible application as a prognostic biomarker in CRC patients
